    Description TECHNICAL FIELD [0001] The present invention relates to the field of watchmaking. More particularly, it relates to a timepiece comprising a pumping mechanism.
    STATE OF THE ART [0002] When the movement of a mechanical watch naturally stops, it is necessary to wind the watch barrel so that the oscillator restarts and the movement functions normally. If the movement is equipped with an automatic winding mechanism, it is nevertheless necessary to start the winding of the barrel by a mechanical winding mechanism that the automatic winding mechanism then relays to fully raise the barrel and maintain the operation of the movement, the unless the watch is worn by a user.
    It is known to realize mechanisms for winding watch movements actuated either by rotation of a winding stem or by translation of a pusher, the latter actuating in translation a winding stem. Pusher winding mechanisms, although less common than those with winding stem rotation, have also been widely described in the prior art.
    These winding mechanisms push allows a user to print by pressing the pusher a translational movement of the latter through an orifice receiving said pusher in the watch case, this movement being converted into a rotational movement of a driving member meshing with a mobile winding of the barrel, for example a ratchet or a toothing of the barrel itself.
    Swiss patents CH 5 578, CH 140 164 or CH 707 985 describe winding mechanisms pushing cooperating in translation with a winding stem which actuates at least one lever member, such as a toothed sector or a rake by example, bearing or having a meshing of meshing of the winding of the barrel. The tooth profile then determines the torque transmitted to the armoring mobile.
    However, it turns out with such delicate mechanisms to allow disengagement of the toothed sector or rake at the end of the winding stem stroke to allow it and the pusher a return to its starting position or rest without driving the mobile arming in reverse or simply without rubbing against the latter with the wear and the risk of blockage that entails.
    The mechanisms described in CH 5 578 and CH 140 164 do not allow to release the mobile winding end of the winding stem without contact of the lever member on the toothing of the latter and therefore are not totally satisfactory and reliable.
    The winding mechanism described in CH 707 985 comprises it a lever member provided with a retractable toothing by pivoting about a fixed axis. Such a construction proves to be satisfactory for allowing the lever member to be disengaged from the armoring mobile but, on the other hand, requires a modular construction of the lever member, which is both complex and functionally random, especially in terms of the reactivity of the lever. the retraction of the retractable toothing of the lever member.
    The present invention aims to provide a timepiece provided with a pumping mechanism of an alternative structure which allow a complete decoupling, fast and reliable of the drive lever member of the mobile phone. arming the movement of the timepiece when the pusher returns to its rest position.
    Disclosure of the invention [0010] More precisely, the invention relates to a timepiece comprising a push-up mechanism comprising a push-button, a movable control member under the action of the push-button and an arranged transmission assembly. for meshing with a barrel winding mobile under the action of the control member, characterized in that the control member is movable between a rest position and a winding position and in that the set of transmission comprises at least one toothed sector whose center is movable along a determined path during the movements of the control member from the rest position to the winding position and vice versa so as to mesh with the armor only during movements of the control member from the rest position to the winding position and to disengage from the winding member during movements of the control member e from the winding position to the rest position.
    This arrangement advantageously makes it possible to provide a winding mechanism for pushing a timepiece whose toothed sector disengages directly and totally from the mobile armature by moving its center along a determined path to move the said toothed sector of the mobile arming. In addition, the components of the mechanism are limited in number, simple geometry and moving parts of the mechanism operate only small strokes in the timepiece, providing a simple and very compact winding mechanism, especially in the the thickness of the timepiece, especially in comparison with the mechanism described in CH 707 985.

    Embodiment of the Invention [0030] FIGS. 1 to 7 a first embodiment of a winding mechanism of a timepiece according to the invention and in Figs. 8 to 11 a second embodiment of a winding mechanism of a timepiece according to the invention.
    On these figs. 1 to 11, only the constituent elements of the winding mechanism are represented for the sake of clarity of representation. It is understood of course that in the context of the invention this winding mechanism is a particular set of a timepiece such as a wristwatch comprising, integrated in a box not shown in the figures and kinematic connection with at least one mobile winding barrel of the timepiece, this mobile can be any conventional type known to those skilled in the field of watchmaking, including any mobile with at least one tooth sector for driving in rotation of said mobile.
    According to the first embodiment shown in FIGS. 1 to 7, the timepiece of the invention comprises a mechanism 1 for pushing up a barrel winding device 5 such as a ratchet or a ring gear, the winding mechanism 1 comprising a toothed sector mounted free to rotate on an axis integral with a plate or a bridge of the timepiece, the plate or the bridge being not shown in the figures.
    The mechanism 1 of reassembly comprises a pusher P, secured to a control member 2 movable in rotation about an axis X1 integral with the plate or bridge of the timepiece under the action of the pusher P between a rest position and a winding position.
    The control member 2 is in kinematic connection with a transmission assembly arranged to mesh with the mobile armature 5 during the rotational movement of the control member 2 so as to cause said mobile armoring R in rotation about a proper axis for, conventionally, storing mechanical energy.
    According to the invention, the center of the toothed sector of the winding mechanism 1 is movable along a determined path during the movements of the control member 2 from the rest position to the winding position and vice versa. so as to mesh with the armature mobile 5 only during movements of the control member 2 from the rest position to the winding position and to disengage from the armature mobile 5 during the movements of the control member 2 from the winding position to the rest position.
    More particularly, in this first embodiment, the control member 2 consists of a first latch 21 pivotally mounted around a first fixed pivot P1 materializing the axis X1, said fixed pivot being formed for example a pin driven on a frame of the timepiece, including the platinum or a bridge of the timepiece.
    The pusher P formed of material with the latch 21 and is preferably adapted to extend, in a conventional manner, at least partially projecting through a hole in the timepiece, in particular in a box of it.
    The transmission assembly comprises a second latch 4 pivotally mounted at a first end around a second fixed pivot P2, also for example formed of a pin driven on the frame of the timepiece. The second flip-flop 4 is further secured to a second end of the armature mobile 5 pivotally mounted at a first end around a first movable pivot Pm1 with which the center of the toothed sector 3 is merged. The second latch 4 is further constrained in rotation about the second fixed pivot P2 by a spring 41 bearing on a stud 8 integral with the plate or a bridge of the timepiece. Preferably, the spring 41 can take the form of a leaf spring formed of material on the body of the second rocker 4.
    As shown in FIGS. 1 to 7, the toothed sector 3 mobile in rotation around the pivot Pm1 can traverse a complex trajectory made of two rotations, a first rotation around itself of the mobile pivot Pm1 and a second circular path, or at the very least following a circle section, centered on the second fixed pivot P2 of the second flip-flop 4.
    The toothed sector 3 is formed at a second end of the armature mobile 5 opposite the first movable pivot Pm1 on which is also mounted a rake 6 free to rotate about the pivot Pm1 and adapted to mesh with a rack 7 secured to the first latch 2. In the example of FIGS. 1 to 7 the rack 7 is formed of material protruding from the body of the first latch 21.
    The rake 6 further comprises a connecting rod (or link) 61 for rotating the toothed sector 3, which extends from the first movable pivot Pm1 and a second movable pivot Pm2 formed for example of an axis 62 driven in a hole provided for this purpose in the connecting rod 61 or a lug formed projecting on the lower surface of the connecting rod 61. The connecting rod 61 and its second mobile pivot Pm2 are arranged to cooperate by bearing the axis 62 in support in a hook 54 formed at the end of a finger 53 for returning the armature mobile 5 so as to drive the toothed sector 3 in rotation about its movable axis Pm1 as will be described later.
    Finally, the first latch 2 comprises at its end opposite to the first fixed pivot P1 around which it is rotatable a finger 22 arranged for, in the at least rest position, bear on a pin or lug 42 protruding on the second rocker so as to tension its spring 41 and thus maintain the toothed sector 3 disengaged from the ratchet R. To do this, the return spring K of the rocker 2 is chosen so that the return constant of the latter is such that the force applied by the finger 22 on the pin 42, taking into account the lever arm formed by the rocker 1 itself, is greater than at least the spring constant 41 of the second latch and resistance applied by the pin 42 on the finger 22 under the effect of the spring 41.
    The kinematics of the winding mechanism 1 according to the first embodiment of the invention will be described in more detail below with reference to FIGS. 2-7.
    FIG. 2 represents the winding mechanism 1 in its neutral position of rest, before and after actuation of the control member 2 by action of the pusher R From this rest position, the winding mechanism 1 is actuated (Figs 3 to 6) by a pressure (arrow F) of a user on the pusher R which generates a thrust force on the first latch 21 forming the control member of the mechanism, greater than the spring constant K of this latch 21.
    Said toggle 21 then pivots around its fixed pivot P1 in the counterclockwise direction, thus releasing finger 22 from pin 42 of second rocker 4, which also pivots on its fixed pivot P2 under the restoring force of its spring 41. , thus initiating a circular movement of the movable pivot Pm1 and thus of the moving armature 5 which moves in order to reach the pitch diameter of the ratchet R to allow meshing of the toothed sector 3 to the ratchet R (FIG 3). When the teeth of the toothed sector 3 are engaged with those of the ratchet R, it is impossible to have a tooth-to-tooth locking due to the flexible structure with double rockers 21, 4 of the winding mechanism of the invention which allows a repositioning in all the circumstances of contact between the arming mobile 5 and the ratchet R.
    The thrust of the pushbutton P on the rocker 2 also induces concomitantly a rotational drive of the rake 6 by the toothing 7 of the first latch 21 around the movable pivot Pm1. This rotation of the rake 6 transmits a rotational movement of the armoring device 5 in the clockwise direction around the mobile pivot Pm1 by means of the rod 61 resting in the hook of the return finger 53 of said armoring mobile. This rotation of the armature 5 thus drives the toothed sector 3 appropriately and by meshing effect the ratchet R in the counterclockwise direction to raise the mainspring (Figure 4).
    When the pressure of the user on the pusher P is released (Figure 5) the mobile armature 5 and its sector gear 3 disengages the ratchet R to return to the rest position. The complete return to the rest position (FIG 6) takes place under the simple return force of the spring K of the first latch 21, which thus fully fulfills its function as the mechanism control member. The application of multiple pressures on the pusher P by the user thus allows the winding of the barrel, or in the case of timepiece with automatic winding, the priming of the winding to restart the movement after a complete stop of the last.
    Advantageously, the winding mechanism 1 also comprises a safety position shown in FIG. 7, especially when the effort to overcome to drive the ratchet R is too important, especially in case of complete winding of the watch cylinder. In such a situation, the arming wheel 5 disengages in order to avoid any breakage. This disengagement is effected by releasing the axis 62 of the rod 61 of the rake 6 from the hook of the return finger 53 of the armoring mobile 5, as shown in FIG. 3. This disengagement of the link 61 thus avoids a too great rotational force is imposed on the ratchet R, which could damage the mechanism of the timepiece. When the push-button pressure P is released, the first flip-flop 1 returns to the rest position under the effect of its return spring K, as well as the second flip-flop 4 and the winding arm 5.
    A second embodiment of the winding mechanism of a timepiece according to the invention is shown in FIGS. 8-11 is described in detail below.
    In this second embodiment, the winding mechanism 100 comprises a control member 200 formed of a rocker 201 rotatably mounted about a fixed pivot P1 'on the plate or on a bridge of the piece of watchmaking. This rocker 201 comprises at a control pushbutton end R substantially opposite its pivot P1. The transmission assembly of the winding mechanism 100 includes a ratchet wheel 500 forming or carrying said toothed sector 300. and an intermediate mobile 600 having a toothed peripheral sector 601 meshing with the ratchet wheel 500 to drive the ratchet R in rotation to raise the barrel spring of the movement of the timepiece.
    The intermediate mobile 600 is arranged to cooperate in rotation with the latch 201 via a control gear 700 pivotally mounted around a second fixed pivot P2 'formed for example by a pin driven on the plate and / or a bridge of the timepiece. The control gear is arranged to cooperate in rotation, and more particularly to be rotated about its fixed pivot P2 ', by the rocker 201 via a stud 701 projecting from a surface of said control gear 700 and forming an abutment against which the rocker 201 is able to bear when the latter is rotated about its pivot PV by pressure on the control pusher P. In addition, a leaf spring 401 formed on a weighbridge 400 adapted to to be screwed onto the turntable of the timepiece also bears at its free end on the stud 701 so that said spring 401 exerts a return stress on said stud 701 opposite to the thrust direction of the rocker 201 when of the rotation of the latter consecutive to a pusher pressure P.
    The kinematic connection in rotation of the control gear 700 to the intermediate mobile 600 is formed by a pinion 602 or a lug formed on the intermediate mobile 600, or arranged on the latter, on which is coupled the order of reference 700 in an opening 702 of complementary shape to that of the coupling member 602. In particular as shown in FIG. 8, the pinion 602 is rotatably mounted on an axis 603 whose one end is secured to the intermediate mobile 600 and the other end is fitted into a hole 402 formed for this purpose in the weighbridge 400. The pinion 602 comprises besides a tooth 604 adapted to abut a lug 605 protruding from the surface of the intermediate mobile 600 in order to transmit a driving torque in rotation of said intermediate mobile about the axis defined by the pivot P2 'of rotation of the control gear 700.
    Furthermore, the ratchet wheel 500 is mounted free around a shape of axis 800 adapted to be screwed or riveted for example on the turntable of the timepiece.
    This shape of axis 800 is advantageously configured to, on the one hand, guide the ratchet wheel 500 in rotation in meshing of the ratchet R under the driving action of the intermediate mobile 600 during a displacement. of the rocker 201 consecutive to a thrust on the pusher P and, secondly, to guide the ratchet wheel 500 following a non-circular path, for example a cycloid or epicycloid trajectory, so that the latter disengages the intermediate mobile 600, and more particularly of its toothed sector 601, to allow the return of the latch 201 to a rest position under the return of the spring 401 of the weighbridge 400.
    To do this, the shape of axis 800 is fixed on the turntable of the timepiece and comprises at least two consecutive peripheral sections 801,802 having a first circular peripheral section 801 for guiding the ratchet wheel 500 to mesh and guide in rotation the ratchet R and a second non-circular peripheral section 802 for guiding the same wheel ratchet wheel 500 to allow uncoupling of the wheel 500 to the intermediate mobile 600 as indicated above.
    To permanently constrain the ratchet wheel 500 bearing against the shape of axis 800 and coupled to the ratchet R a spring blade 900 is fixed integrally on the turntable of the timepiece. This leaf spring thus forces the wheel 500 to slide on the circular section 801 of the axis shape 800 during the movements of the rocker 201 from the rest position to the winding position and to roll on the non-circular section 802 when the return of the rocker to the rest position, said latch 201 being biased to the rest position by the spring 401.
    The kinematics of the winding mechanism 1 according to the second embodiment of the invention will be described in more detail below with reference to FIGS. 9 to 11.
    FIG. 9 represents the winding mechanism in its rest position. In this, the ratchet wheel 500 bears on the circular section 801 of the axis shape 800 and its toothing meshes with that of the ratchet R. At the same time, the peripheral toothing 601 of the intermediate mobile 600 engages also that of the ratchet wheel 500.
    During a pressure of a user on the pusher P of the latch 201 to initiate a winding action (FIG 10) said latch 201 pivots about its fixed pivot P1 'and pushes on the stud 701 of the reference 700, thus deforming the leaf spring 401 and rotating the intermediate mobile 600 about its pivot P2 'via the pinion 602. The rotation of the intermediate mobile 600 induced by its toothing 601 a rotation drive in the counterclockwise direction of the ratchet wheel 500 around the shape of axis 800 by sliding on the circular section 801 thereof and consecutively a clockwise rotation of the ratchet R. At the end of rotational stroke of the rocker 201, the mobile intermediate arrives at the end of the winding stroke and its teeth 601 disengages from that of the ratchet wheel 500 as shown in FIG. 10.

    [1]
    From the end position of reassembly of FIG. The return of the rocker 201 and the intermediate mobile 600 is done under the restoring force of the spring 401 on the stud 701 of the control gear 700, which drives the intermediate mobile in rotation counterclockwise about the pivot P2 This rotation involves engagement of the toothing 601 with that of the ratchet wheel 500. The return force of the spring 401 is greater than that of the spring 900, the wheel 500 is then pressed against its inner ring against the non-circular section 802 of the axis 800, which tends to move the teeth of the 500 of the wheel 601 of the intermediate mobile and thus to release the teeth of the toothing 601 of those of the wheel 500, thus allowing the return to the rest position of the rocker 201 and the intermediate mobile 600 without forcing on the ratchet R in the opposite direction to that of winding the mainspring.
